HIGH
Type:
CWE-319 Cleartext Transmission of Sensitive Information

Description

TP-Link has identified a vulnerability in Tapo L535E v1.0 and v3.0, Tapo P300 v1.0, and Tapo D100C v1.0, where Bluetooth communication during the initial setup phase is transmitted in cleartext without encryption. Bluetooth is only used during initialization.<br /> <br /> An attacker within the Bluetooth range could exploit this behavior using Bluetooth sniffing or man-in-the-middle techniques, which may allow eavesdropping on Bluetooth communication, manipulate transmitted setup data and potentially gain unauthorized control of the device during initialization. <br /> <br /> <br /> An attacker<br /> within the Bluetooth range could exploit this behavior using Bluetooth sniffing<br /> or man-in-the-middle techniques, which may allow eavesdropping on Bluetooth<br /> communication, manipulate transmitted setup data and potentially gain<br /> unauthorized control of the device during initialization.<br /> <br /> <br /> <br /> D100C is the<br /> chime delivered with your Tapo camera, and it is delivered with the following<br /> Tapo products:<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> D130, D210, D235,<br /> D225, TD21, TDB21 and TD25
